Breaking news: After a long delay, Sajax version 0.12 is finally out. PHP support has been much improved, including many bug fixes and improvements to the serialization support. Please download the new version and contact us if you find any bugs.

Sajax is an open source tool to make programming websites using the Ajax framework — also known as XMLHTTPRequest or remote scripting — as easy as possible. Sajax makes it easy to call PHP, Perl or Python functions from your webpages via JavaScript without performing a browser refresh. The toolkit does 99% of the work for you so you have no excuse to not use it.

Version 0.9: Fixed bug in Perl backend — thanks to Max Maischein. Major restructuring of PHP backend: incl_sajax.php is now Sajax.php, rs_* functions are now sajax_*, added sajax_get_javascript() which doesn't echo output, created generic XmlHttpRequest dispatcher function to minimize code duplication — thanks to Majeed Goldrick.

Version 0.4: Remove old, unused objects; fixes for Wall example.
Version 0.3: Inline, anonymous function for onReadyStateChange is the cure to global ills; performance much improved.
